Question

complete the following table to demonstrate the differences in function between peroxisomes, vacuoles, and endo organelles. answers may be used more than once.

organelle	function	associated proteins origins
vacuoles
endomembrane organelles including the golgi apparatus

options (for function and associated proteins origins):

• free ribosomes within the cytoplasm
• rough endoplasmic reticulum
• contain enzymes associated with lipid metabolism
• provide storage of water, sugars, salts, pigments, and toxic molecules
• transport, modify, and package proteins

Explanation:

For Peroxisomes:

• Function: Contain enzymes associated with lipid metabolism (Peroxisomes are involved in lipid metabolism and detoxification, and they contain enzymes for these processes, including those related to lipid metabolism).
• Associated Protein’s Origins: Free ribosomes within the cytoplasm (Peroxisomal proteins are mostly synthesized by free ribosomes in the cytoplasm and then imported into the peroxisome).

For Vacuoles:

• Function: Provide storage of water, sugars, salts, pigments, and toxic molecules (Vacuoles in cells, especially in plant cells, are known for storing various substances like water, nutrients, pigments, and also sequestering toxins).
• Associated Protein’s Origins: Free ribosomes within the cytoplasm (Most vacuolar membrane proteins or associated proteins are synthesized by free ribosomes in the cytoplasm and then targeted to the vacuole).

For Endomembrane Organelles (including Golgi Apparatus):

• Function: Transport, modify, and package proteins (The endomembrane system, including the Golgi apparatus, is responsible for processing, modifying, and packaging proteins that come from the rough ER, as well as transporting them to their destinations).
• Associated Protein’s Origins: Rough endoplasmic reticulum (Proteins for the endomembrane system are initially synthesized on the rough ER, where ribosomes are attached, and then move through the endomembrane system for further processing).

To present this in a table format (as requested in the problem to complete the table):

Organelle	Function	Associated Protein’s Origins
